Exploring the Possibility of Interacting Quintessence Model as an Alternative to the $\Lambda$CDM Model

Abstract

This study examines interacting quintessence dark energy models and their observational constraints for a general parameterization of the quintessence potential, which encompasses a broad range of popular potentials. Four different forms of interactions are considered. The analysis is done by expressing the system as a set of autonomous equations for each interaction. The Bayesian Model Comparison has been used to compare these models with the standard Lambda Cold Dark Matter ({\Lambda}CDM) model. Our analysis shows positive and moderate evidence for the interacting models over the {\Lambda}CDM model.
